I'll NAQ this one.

As a result of the separate lkml thread:

  Inquiry: Should we remove "isolcpus= kernel boot option? (may have realtime uses)

and as a result of there not yet being a good reason -to- remove this,
other than a few kernel developers who don't like it, I conclude that
we should not just remove the "isolcpus=" feature.

It might be that we should deprecate it, as I have suggested in the
past.  But I'm not now seeing even a good reason for that.
